l/VATER-CIBCULATING ATTACHIEENT FOR INTERNAL-COMBUSIION ENF-LINES.

Application filed March 28, 1923. Serial No. 628,267'.

To all whom it may conce/rn:

Be it known that I, Go'r'rnin MULLER, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Tsl'latcr-Circulating Attachment for Internal-Combustion Engines, of which the following is a specification.

My invention consists of a novel construction of an auxiliary water circulating device which can be readily attached at a small expense to existing motors or internal coi'nbustion engines of a standard or con ventional type, whereby the circulation in the cooling system is effectively augmented, so that liability of overheating the engine is by my invention, reduced to a minimum, or entirely obviated.

It further consists of a novel construction of an auxiliary pulley, and novel means for attaching it to the standard engine shaft pulley which drives the radiator cooling` fan. i

It furtherconsists of a novel construction of propeller' employed.

It further consists of other novel features of construction and advantage, all as will be hereinafter pointed out.

For the purpose of illustrating my in vention, I have shown in the accompanying drawings forms thereof which are at present preferred by me,4 since they will give in practice satisfactory and reliable results, although it :is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organizations of these instrumentalities as herein shown and described.

Figure 1 represents a side elevation of water circulating attachment for an internal combustion engine, embodying my invention.

Figure 2 represents a front elevation of Figure 1 with the radiator, fan and their adjuncts removed.

Figure 3 represents on an enlarged scale, a front elevation of the auxiliary'pulley body and its adjuncts.

Figure l represents a section on line /l-l Figure 3, certain of the parts being shown in elevation.

Figure 5 represents a back view of the lower portion of the auxiliary pulley body seen in Figure 3, showing the contour of the wedge receiving' pocket therein.

Figure G represents a perspective view ot one of the bolts and wedges employed in detached position. y

Figure 7 represents on an enlarged scale a vertical sectional view of the propeller.

Figure 8 represents an end view of Figure 7.

Similar numerals of reference indicate corresponding parts in the figures.

In carrying out my invention I attach to the pulley 1 of the engine shaft 2 of a motor the auxiliary pulley which comprises an open ended casting or body 3 having thc annular groove l, and the shoulder 5 which abuts against the outer edge of the pulley 1, and is held ixedly thereto by the blocks or wedges 6 through which the bolts 7 pass, said wedges having inclined walls which engage the pockets 8 on the rear or inner wall of the casting or body 3. By having` the auxiliary pulley detachable and at the same time at the front of the engine shaft 2 it is possible to readily make adjustments and apply the drive belt 30.

I preferably make the pockets three in. number and slightly thicken or reinforce their walls, as indicated at 9, inFigures 3 and 4. It will be seen from Figure il, that when the bolts 7 are tightened, the blocks or wedges 6 are drawn tightly against the juxtaposed inner walls of the pockets 8 and the pulley 1, so that the latter and the auX- iliary pulley or body 3 are firmly locked together and rotate as a unit.

10 designates the belt whereby power is transmitted from the pulley /1 to the pulley 11 mounted on the shaft 12 which carries the propeller 13 whose relative position with respect to the circulating pipe 141 will be understood from Figure 1. The belt 10 passes over the idle or belt pulley 15 mounted on the shaft 16 which is carrie-d on the arm 17, which is pivotally connected to the arm 18, which is mounted on the stud 19. Any suitable form of belt tightener may be employed and as the general construction and mode of operation of these belt tightening devices are well known, it is not necessary to describe the same in greater detail. By having the arm 17 adjustably supported at its inner end it, is possible to move the idler 15 toward or away from the engine shaft 2 in order to tighten or loosen the belt blades or vanes 22 and 23 whose contour will be understood from Figures 7 and 8. These blades are of spiral shape and the y outer or front edges 241 of said blades, as inedges dicated in full lines in Figure v8, slightly' overlap or are out of alignment with the in the rear thereof, see dotted lines in Figure 8. Y

The propeller shaft 12, and the propeller 13 are mounted in the fitting 26 which forms a part of or is secured in the circulating pipe 14 approximately as seen in Figure 1, and it will be understood that the rotation of said propeller will cause the requisite circulation from the bottom of the vradiator 27 upwardly through the pipe 141, Water jackets 28 and outlet pipe 29 to the top of said radiator, thereby preventing the motor from overheating. Y

It will be understood that the pulley 1 drives the belt 30, which drives the fan shaft 31 and the fanv 32, which parts are of the usual conventional type. l

My invention is especially adapted lto the most extensively manufactured motor car of the present time, Without any change or dismantling of the standard equipment,

since it is only necessary to supply the auxiliary pulley body, bolts, Wedges, propeller' and their adjuncts, and assemble them as above described, whereupon the Water cirwhat I claim as new and desire tosecure byV 4Letters Patent is Y In a combination an internal combustion engine having a Water cooling system including a radiator and an inclined circulating pipe extending upwardly from the radiator bottom, a'fitting for said pipe forming a propeller shaft bearing, an engine'shaft, a

fan belt pulley on the latter, an auxiliary grooved pulley detachably connected to the front of said fan beltV pulley, a propeller shaft having a bearing in said fitting and,

horizontally extended therefrom, a propeller arranged in said fitting and ixedto the propeller shaft for positively circulating water through said pipe .direct from the radiator' bottom to the radiator top, a pro-.p

peller shaft pulley, a belt connecting said engine shaft and'propeller shaft, an idler` over which the'p'ropeller'shaft belt travels,7

and an arin' adjustably supported at one end and carrying said idler at its other end, said auxiliary pulley, idler and propeller shaft pulley being in the same vertical plane and in advance of said fan belt pulley.
